Key Features
- 6-position dual-row layout on ultra-fine 1.27 mm (0.050 inch) pitch enables very high contact density in space-constrained SMT designs
- High-reliability contact design meets demanding mating-cycle and environmental standards for aerospace, defense, and industrial applications
- Elevated height (H) body configuration provides inter-board clearance for stacked PCB assemblies with components between boards
- Tape-and-reel (TR) packaging with factory-applied orientation coding supports uninterrupted automated pick-and-place SMT production
Applications
The SAMTEC SFM-103-L2-H-D-A-K-TR is designed for high-density board-to-board signal connections in space-constrained applications such as aerospace avionics modules, defense electronics, and compact medical instruments requiring a 6-position, 1.27 mm pitch surface-mount socket. Its high-reliability contact design and elevated body height accommodate precision mating headers while maintaining clearance above the PCB surface for underlying passive components. The tape-and-reel packaging and SMT termination make this socket compatible with automated reflow assembly lines used in high-mix low-volume and high-volume production environments.

Frequently Asked Questions
What is the pitch and position count of the SFM-103-L2-H-D-A-K-TR, and why does this pitch matter for dense PCB layouts?
The SFM-103-L2-H-D-A-K-TR is a 6-position dual-row socket on a 1.27 mm (0.050 inch) pitch. At 1.27 mm pitch, the dual-row footprint occupies roughly 3.81 mm of board length for 6 contacts, compared to 7.62 mm for an equivalent 2.54 mm pitch socket. This 50% space reduction is critical in compact modules such as avionics line-replaceable units and medical sensor packs where every square millimeter of PCB area is constrained.
What elevated height body clearance does SFM-103-L2-H-D-A-K-TR provide, and which designs benefit most?
The elevated height (H) body raises the socket above the PCB surface, providing approximately 4 mm to 5 mm of inter-board clearance when mated, which accommodates 0402 and 0603 SMD passives, bypass capacitors, and low-profile ICs positioned beneath the connector. Stacked PCB modules in compact instruments and defense electronics benefit most, as this clearance eliminates costly PCB keep-out zone routing constraints below the connector footprint.
How does the high-reliability contact design of SFM-103-L2-H-D-A-K-TR compare to standard commercial-grade socket strips?
SAMTEC SFM high-reliability contacts are designed for extended mating cycles typically rated at 50 or more insertions with contact resistance below 30 mΩ, compared to 10 to 25 cycles for standard commercial socket strips. Gold-plated contacts and tighter dimensional tolerances also reduce the risk of contact fretting in vibration environments, making this 6-position socket suitable for military-grade hardware and avionics equipment subject to MIL-STD-810 vibration and shock specifications.
Is SFM-103-L2-H-D-A-K-TR a lower position-count option to SQT or TSM connector families, and when should designers prefer it?
The SFM series operates at 1.27 mm pitch versus 2.00 mm (SQT) or 2.54 mm (TSM), making SFM-103-L2-H-D-A-K-TR the preferred choice when PCB real estate is critically limited and fewer than 10 positions are needed per connector. Designers should choose this 6-position SFM socket when signal count is low but density is paramount, while SQT or TSM variants suit higher position counts on less constrained boards.
